Effect of magnetic field on electrochemical polymerization of EDOT

M.S. Cho, Y.Y. Yun, J.D. Nam, Y. Son and Y. Lee

Abstract

Poly(3,4-ethylenedioxythiophene) (PEDOT) films were synthesized by electropolymerization under an applied magnetic field on ITO glass. The effects of the magnetic field on the electrochemical polymerization of EDOT and the redox behavior were examined. The cyclic voltammetry (CV) result indicated that the applied magnetic field exceedingly accelerated the polymerization rate. The effect of the conformation of the PEDOT chains under applied magnetic field was studied by Raman spectroscopy. Scanning electron microscopy (SEM) showed the morphological changes of PEDOT film in the presence of the magnetic field. The parallel applied magnetic field induced the formation of more expanded chain structure as well as sharp crystalline morphology.
